The AirTAC GC400C15MC2WK AirTAC F.R.L. Combination, PT1/2 is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC400C15MC2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This configuration is sized 400 with PT1/2 ports (PT thread is the standard; G and NPT are order options), carries the 5 um filter element instead of the 40 um standard, uses a manual drain on the filter bowl, and is fitted with an external round gauge reading in psi. The reverse/check valve (code K) is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with a choice of drain type, filter grade, gauge style and scale, thread option and check valve, so a set can be matched to the line it feeds. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). Because flow is published as curves rather than a single rating, we confirm flow and datasheet figures on request before you order.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). The combination has no separate bracket code — the three units couple together with their own mounting hardware. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF400-C1 filter, GR400-C1 regulator and GL400-C1 lubricator.
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Feeding spray guns and air-assisted applicators on a paint line: the 5 um element and water removal protect finish quality, the regulator holds a stable gun pressure, and the lubricator mists oil into the air stream for gun and tool life.
Supplying the pneumatic cylinders and grippers on a packaging conveyor: clean, regulated, lubricated air keeps the seal-and-fold motions consistent through a full shift, with the manual drain emptied during scheduled changeovers.
Feeding the clamps, air springs and tool-changer actuators on a machining centre: the check valve holds the set circuit against supply dips, the regulator fixes clamping pressure, and the 5 um grade protects the machine's pneumatic valves.
Start with the size and port: 400 is the third step in the 200/300/400/600 range, and the port here is PT1/2 - step up a size if the downstream cylinders, valves or tools need more flow than the 1/2 in set can pass, and ask us to check the flow curve against your demand. Choose the drain type: manual drain (this unit) means someone opens the bowl drain periodically; automatic drain suits unattended installations. The filter grade here is 5 um (code W) for finer particulate removal; 40 um is the standard element if coarse protection is enough. The gauge fitted is the external round type reading in psi; embedded square gauges and MPa or bar scales are the other catalogue choices. Thread is PT as standard, with G (BSPP) and NPT available to order. A bracket is included with this unit.
One honest note on sizing: AirTAC publishes flow for this family as curves, not a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the sizing against the datasheet curves before you order.
Quick checklist
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR400-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for the GC family as performance curves rather than a single rated figure, so we do not quote a flow number. Send us your line pressure and the air demand of the equipment you are feeding, and we will confirm the sizing from the datasheet curves on request before you order.
M is the manual-drain code: the filter bowl is emptied by opening its drain by hand, which suits attended installations on a maintenance schedule; automatic and differential-pressure drains are the catalogue alternatives. The trailing K means a reverse/check valve is fitted, so the downstream circuit is held against supply loss.
